J1850 arduino download - ELM327 OBD to RS232 Interpreter - Elm Electronics
An OBD2 compliant vehicle can use any of the five communication protocols: SAE J1850 PWM, SAE J1850 VPW, ISO, ISO Other nonOBD2 protocols
Finally I modified my RohdeSchwarz FSH6 spectrum analyzer to run from a LiIo battery instead NiMH. Dying batteries are an annoying problem of the old RS FSH36.
This active high output is used to drive the J1850 Bus Line to an active (dominant) level for J1850 PWM applications. If unused, this output can be left
J1850 OBDII FORD SCP PWM Documentation Needed PIC Project You can download those documents on SAE webpage, J1850 OBDII FORD SCP PWM Documentation Needed.
Arduino OBDII Interface. I worked on an independent study project creating an Arduinobased OBDII Download the presentation I gave on this project.
AVR J1850 VPW interface All you need is to convert the J1850 and used it as a learning experience to rework it just a little to work on the Arduino.
